Fig. 2From: A multifaceted implementation strategy versus passive implementation of low back pain guidelines in general practice: a cluster randomised controlled trialProbabilistic sensitivity analysis. A probabilistic sensitivity analysis with 5000 bootstrap replications confirms that the MuIS is cost effective compared to the PaIS. The effects are calculated as the probability of not being referred in the MuIS group minus the probability of not being referred in the PaIS groupBack to article page
